.To all whomy 'it may com'.eT11..--Y e Be it known that I, SAMUEL S. HARPER, o citizen ofthe United, States, residing in the city of Philadelphia, coilnty of Philadelphia undState of Pennsylvania; have invented a certain new and useful 'Improvement in Railrod-Ties, of which the following is it description.

The present invention rela-tes to improvements railway ties formed of concrete or cement-molded about an internal metallic core. 10..

The objects ofthe invention are to reduce-the costV of manufacture, to reduce the Weight of the 'tie,.nd"..

to renderl it easily and readily applied` in use. 'I he first of these objects is secured by reducing the amount of e cylinderoi comparatively large diameter. In

of rnetstlwithin the tie to the smallest possible amount. The metal core is hollow, end preferably inthe shepe order to reduce the weight the concrete or cement vwithin the cylindricol metal portion is cored out, ex-

cept that portion immediately' below the rails." This portion of the tie is solid, as it mustI begin-all: of the weightof railsan'd traic.' In order to render the tie easily placed in' position, the metal plates upon which 'the rails rest .are provided with integral ears, which' may be bent over the flnge ci the rail by'an 'ordinary spike maul, so as-to hold the'rail in position without the need of bolts, or other separahleattching media. V In order lto better understand the nature of theinventionf'ttentio'n' is-'directed to .the accompanying drawings, which illustrate one embodiment of the inf vention,` and i'nwhich Figure lrepre'sents 'a longitudinal sectional view'of l vthe tie'takenkon the lines lll-l'of 2; Fig. 2 represents "a" transverse sectional view ofthe tie taken on 'the lines of Figi.. l1; Fig, S'represents a side View of the inter-l v vLnal' core; and'fFigQ 4- represents a`pe1spctive `View of 'e 'In all ofthe severel v i ws like parts are designated bythe semegnuinerals' of reference... i

The-cncreteor cement portion 1 of the' tie is molded `in the usual shape about-the core 2. Theicore is of thin metal, preferably cyliidrical in. shape,v of compams ltively large diameter, and is provided with 'o'great many lips 3, which 'maybe integral, land struck'up out ofthe metal end bent, ;isshown'i` These lips are for the. purpose of 'serving as 'a support for the cemennend ml'y be all of the same size, but they are 'preferably mede as shown in Fig. 2, those which are opposite the comers of the tie beinglOIlger than the others, sothat thecorners will be moreeffectively supported.

The tie is pref-A l'. erztbly cored out et 4 except thefportions 5, 5 immcdi? etely below the rails'. The rails are secured iniileice by -means of the clips ,6, lwhich are `mode of hesvy' sheet ,metsth'iind have ears, 7, 8, whichfcngage with the' rail ,nndfmey be bent over the flanges. to ,hold-itin place. l

The ears may be bent orithe flange of the'rili-byham-eV meting, s'tsby a-spike ma'ul. As shown in thedrawf ings, theclips are provided with three ears', .to engage with the inside of thwsil, and with -bt two em sv4 on the outside.V The strain upon the inside isdn verti- ,ctldirectiom and for 7this reason .three ears are used on this portion of the clip..

lIn order to dd'to'the strengthl of v.the structurejhe ears 'T-upon the inside orthe ears 8 on the outside, or(` both, ofthe clip may be corrugated ns shown at 9. On theoutside o'f the clip a'reverse for depending-eur 10- may'be arranged which will .be"enibedde d Within lthe cement. The dependingle'ar is for the'purpose of resisting horizontal movement of the' clip. The rail may -be removed by bending the ears and releasing them from engagement with therv rail; flange by means lof a crowb'r orothe'r tool. .Esch of the clips 'issecnred' in placeby being provided with securing members, :is two vbands 11 'which pass `around 'the lvsides of 'thel tie lsind arev interlocked at 12.1 The clips rest within depressions 13 within the top of the tie, and the two bands may be embedded Within the tiev a short distance; olthough .this-is not necessary: If for vmy reason it "becomes necessarylto tighten the bends, a shim may be driven between one of them and the tie,- and il' the-clippecomes 1oose,or depressed within the top of the tie 'so thatfthe rail becomes out o alin'emen't, a. shimiiiay be driven between the clip and the tie. c

' 'Il prefer to mold-the clip in' place upon ther'tie, but

Athis isnot essentialas the clip may applied after-y wards; In order to secure the hollow centerv of the' tie with the solid portion on each side thereof, it-may be molded' in sections, 'with 'one of the solidv portions eif't'erwgirds` 'introduced in the form of a plug.

It be noticed thatthere is no break in the .upper Y surface or sides of the tie as would be the case if the mil were attached by means' which `passes through the v.vio

tie.' For this reason it isimpossible for water torposs/Y into the tie and cause destructive effects, as byfreezing,

or corrosion.

As before described, the core 2 is hollow, and of c0111-,

paratiiely large diameter. By the term flnrge dinmeter, I desire it understood that I menno construction v zherein the cement vwilll be cored out ,L and 'still as to c a'use no appreciable diminution -of the weight 'of the tie. Any form o concrete or 'cement m'aiy bp used,

, tached to that paitof the tie which is slid.' 'llhe portionfwill, therefore.l 'be under the mil andthe will be supported by the strongest oi Yleave a considerable thickness ofcement within thecore, .withontreqering that' the central opening be so small 4`strengthening the tie.

` point. ol greatest strength oi the tie will also additionally reinforce it at the point at which it is subjected to the rEhe two bands il which bass around the side oi the tie and secure the clip in place also conti'tute means for The clip being attached' to the new and desire to secure 'by Letters Patent, is:
